Abstract: In this study, a new market structure is designed for frequency related ancillary services namely load following and frequency regulation. This structure is also in compliance with NERC (North American Electric Reliability Council) control performance standards and reduces the wear and tear of generating unit`s equipment. Three-area test system is used to illustrate the proposed methodologies. The model is simulated using Matlab Simulink tool box for three area system and results are obtained . The performance of the structure is investigated using ramp with random load disturbance. In addition to load disturbance, the contract violation issue is also analyzed. Two sets of case study results are reported. The first case study analyses the performance of the conventional controller with high control parameter and the second case study simulates the design of fuzzy tuned controller. The effectiveness of the above two cases for an interconnected power system is compared. The simulation results show that the fuzzy tuned market structure is better in reducing wear and tear of the generating unit`s equipments and how the generation can be shared among the Genco`s with and without contract violation.
